Stop screws from coming loose due to light vibration while protecting your mating surface from damage. These screws have a split lock washer with uneven ends that bite into the screw and the flat washer. Also known as Sems screws, the washers rotate freely but are permanently attached. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
